Edit Map Capabilities

I would love to see more map editing capabilities. Here's my reasons for this capability.

• Sometimes I forget to press start until I'm 1/2 mile down the road.
  
• If I run underground (subway or buildings with underground areas) the GPS looses signal but we could update the map to actually where we went.
  
• When riding on a trainer or running on a treadmill the map often jumps around a bit. You could correct this.
  
• Alternatively you could set the map to (when on trainers or treadmill) to "city view" so it would mark you exact location (like home). Would help for privacy reasons.
  

Thanks for all you guy's work.
